Tornadus (Japanese: トルネロスTorunerosu) is a Flying-type Legendary Pokémon first introduced in the Generation V games Pokemon Black and White. It is also a Pokémon that is only a male. You have to go to route 7 and go into a house and when you come out there is Tornadus. It is somehow related to Thundurus and Landorus. It is a version exclusive for Pokémon Black. If Tornadus is in the same Route as you, it will start pouring rain. The message boards will sometimes say: a mysterious storm has appeared in Route (any route really) and this means that Tornadus is in that Route.

Tornadus' name is a combination of the English words "tornado" and possibly the end of "Enceladus," who was a giant in Roman and Greek mythology.

In the Djinn trio Tornadus is the only one who is not a dual type.

Tornadus and the rest of the Kami trio will have 3DS and AR searcher app exclusive forms that can be sent to copies of Pokemon Black 2 and Pokemon White 2, called "Therian Formes", while their current forms are called "Incarnation Formes"

It's Therian Forme is the mystery silhouette in the AR searcher app picture.

While Tornadus has a gender, it cannot breed because it is still a legendary.

In Pokemon Dream Radar, Tornadus appears as one of the legendary Pokemon of the game, but, unlike the rest of the Kami Trio, is encountered twice. The first time is when the player completes a research for the first time, where Tornadus appears to the player, but cannot be battled, as Tornadus flies away. The second time is when the player opens up the extension. This time, Tornadus is battleable.
